A standard triathlon consists of a 0.93-mile swim, a 25-mile bike ride, and a 6.2-mile run. Skylar has already completed the swim and the bike ride in 3.5 hours. If Skylar runs a 12-minute mile, approximately how long will it take her to complete the triathlon?

Answer:

about 4hours and 45 minutes

Explanation:

> Standard triathlon

0.93-mile swim, and 25-mile bike ride in 3.5 hours

6.2-mile run in ? hours

> If it takes (12-minute/ 1mile) then will have (? minutes/ 6.2 miles.)

So we need to find an equivalent fraction of 12/1 that has x/6.2.

(12min/ 1 mile) = (x minutes/ 6.2 miles) , cross multiply

1*x = 12*6.2

x = 74.4 minutes will take to run 6.2 miles

> The rest of the ride times are given in hours so will convert or minutes to hours

60 minutes = 1 hours

74.4 minutes = x hours

x= 74.4 *1/ 60 = 1.24 hours

x = 1.24 hours will take to run 6.2 miles

> Approximately how long will it take her to complete the triathlon?

0.93-mile swim, and 25-mile bike ride in 3.5 hours

6.2-mile run in 1.24 hours

3.5 +1.24 = 4.74 hours which is about 4hours and 45 minutes
